中文摘要：

计算发现北半球高海拔地区树轮重建的温度序列和具有温度指示意义的祁连圆柏树轮宽度年表均与南半球Quelccaya冰心δ^18O序列年际间显著相关，r=0．13~0．22（p〈．0001）。40年滑动平均后，序列之间相关关系大幅度提高，甚至高达0．74（p〈0．0001）。树轮宽度和冰心δ^18O不同的记录载体传达了共同的信息：南北半球高海拔地区温度变化存在很强的高频和低频振荡遥相关关系。

英文摘要：

By calculating, it is found that there is significant correlation between ice core δ^18O series from Quelccaya in southern hemisphere and the reconstructed temperature series by tree rings from high-altitude of Northern Hemisphere, as well as ring-width chronology of Sabina przewalskii which is temperature indicative, with r=0.13~0.22 （p〈0.0001）. After 40-year＇s moving average, the correlation coefficient improved greatly, even up to 0.74 （p〈0.0001）. Common information derived from tree-ring width and ice core δ^18O together indicates that there are strong tele-connections in both high and low frequency of temperature variations in high-latitude areas between North and South hemispheres. It may suggest there are some linkages between Asian Monsoon circulation and Asia-Pacific Oscillation （APO）, ENSO and other climate events （An and Thompson, 1998）. It also shows the representativeness of temperature variations in Tibetan Plateau of China for large region scale （Asia or hemisphere）.
